Associations between the bovine PPARGC1A gene and milk production traits
Kowalewska-Łuczak, I. | Kulig, H. | Kmieć, M.
The aim of this study was to investigate associations between PPARGC1A genotypes and haplotypes and milk production traits. The study included 181 Jersey cows. The genotypes were identified by the PCR-RFLP method. The frequencies of the most common alleles were as follows: T – 0.63 (c.1892T>C) and A – 0.88 (c.3359A>C). The frequency of the most common haplotype was TC/AA – 0.558. The results showed that there were no statistically significant associations between the individual genotypes of both SNPs and milk traits; however, individuals with the CC/AC haplotype produced significantly (P ≤ 0.05; P ≤ 0.001) less milk and had a significantly (P ≤ 0.001) higher protein content in milk.
